A it known ihnt L VTLLIAM En 511 s v v o! Hlinois, have inventq in} improvement in Miami l-a SuiIsvny-(furs, of which the foiiowing u unification.

My invention relates to doors that are dnawihrd with corrugated meta} and the obivvi is to produce a light, very strong, rhea}; door, having the 111i. its and novelty herein set forth and claimed.

Rvfm'enco will he had to the accompanying droning in which-- Figure 1 is an uiovntion of my door mounted on fho side of a war.

in a transverse. section arross tho Wi li} of tho door.

in? doors should he as light as {)Ofifi'ihh in! tho runson that they must ho o nonisd nod vhmvd under unfavorable vondiiions and shoidd move on their hangings easily.

Further. freight ears are suhiovied to sma-rr and prolongud 215%" and tho Tush-min m mm; support the door on th wugo in a ('m'i'ndv and rot at tho iioii; mid wrew imhrfl, so Holt zii'tor Very long use the weight of :hrdoor is a surions strain on tho wonkonod fast-"ohms which 1mm it to the our.

Further, doors of this ohms are gmoti nhmzod in opening and in closing them :1 nd mr nes placed against them or failing a; m; them in transit tax to the utmoai. thy airongth of tho door in every Way.

it oi'tc-n happens that rorgo gets wodgoii :lgoiiiqt. the inside of the door and this makes a door hard to open and hence aharp Murders or edges on the insii'le of a: door should he avoided as much as ossihie.

I prefer to make the body of my door (mi, of :1 vurficallpcorrngated sheet.

i prefer to make my oorrugafions whiz flfll v'ti'illQS or summits 3' having roi'wdvd with. rather sharper and nnrr-mizi- 5H; summits of the mirruguiions as ii=di= by 5.

The ends: of thov cross girdem made of the bars 19 and 20 which I designato as 22 when riwtod together are secured by rivets 23 to the vertivnl channel bars 6 and 7 at tho vertimd edgos of the door.

The hangers and door fnstenings are of the usmd typo.
